To ALL wHoM Ir MAY conocen:

Be it` known that we, L. C. BIGNALL and M. C. BIGNALL, both of Medina, in the county of Orleans, and State of New York, have invented certain new and useful improvements in Cast-Iron Sinks; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a central longitudinal vertical section.

Figure 2, an enlarged view in section of one corner of sink basin, and that portion of the wood-work upon which it rests. f

Figure 3, a plan view of one corner of the sink basin.

Like letters represent corresponding parts in all the ffigures.

Our invention relates to that class of sinks which are constructed of cast iron; and it consists in constructin g the sink with a grooved or recessed flange around the outer andA upper edge, to receive the ends of the boards by which it is supported, and forming the outer corners with right angles, while the interior corners are rounded, as hereafter described, by which the ordinary framework is dispensed with; also, in casting or formingft'lie sink constructed as aforesaid with an extension projecting horizontally beyond the sink basin, for the piirpose of receiving a wooden shelf or seat to form a rm base or platform for the pump in combination with the sink, thereby dispensing with the cost of the usual separate frame for supporting the pump.

As represented .in the drawings, A is the sink basin, B the wood-work upon which it rests, and I an extended portion cast with the basin, and of suiiicient size to receive a wooden seat, C, which is iirmly secured in its top by-screws, or in any Aothersu'itable manner, so as to form a strong and unyielding support for the pump D, which is fastened thereto in any proper and ordinary manner. The wood-work, which forms the support for the sink basin, is usually made of boards placed upright, and which are kept in place at their top by means of lawooden frame to which they are fastened. It is one object of our improvement to dispense with the use of this frame, and thereby save considerable labor and expense, by making the sink with a flange or rim, a, around the upper and outer edge, which is concave or grooved on the under side, as represented in figs. 1 and 2, and rounding or otherwise forming the upper ends, b, of the boards of the wood-work, so as to t therein. The weight of the sii'xk resting on the top of the boards holds them rmly together and in place, answering every purpose of a frame, and dispensing with the cost thereof, as the boards have only to be cut of the properlength and set in place, being secured to the floor by a single strip, f, forming a base. We make the outside or iauge portion of the sink with right-angled corners, c, as shown in iig. 3, so as to correspond with the square or rectangular top of the wood-work upon which it rests. This enables the Wood-work to be built with great ease. and economy, itbeing made of narrow strips of stuff, tongued and grooved together, so that .the corner can be formed without framing to a postor working on a circle, to conform to the usual form of iron sinks, which are preferably made without angles to be more conveniently cleaned. But the corners of the bottom are rounded, as also shown most clearly at d in iig. 3, to enable the sink (as before stated) to be more easily cleaned. 'This rounding of the interior of the corners may extend to the top of the sink, if desired, and produce the same eii`ect,provided the rectangular corner to the iiangc is preserved. The pump,'which is used with a sink, has heretofore been ordinarily attached to an' independent frame, separate from the sink, and placed at one end thereof, which occasions additional labor and expense; Y and, owing to the lightness of the material, it is a matter of some diiiculty to construct a frame which shall be suiiiciently firm to form a proper :support for the pump. In the use of our improvement, the frame or platform I for the pump, being rigidly secured to the basin A, by beingeast with it, as before described, forms, with its top or seat, C, also firmly fastened, a most reliable, compact, and substantial support for the pump; and being so attached to the basin, its foundation isl that of the sink itself, the greater gravity of which, being made of cast iron, renders the support for the pump still more iirm and unyielding. By vthis construction, we not only avoid the labor and cost of an extra frame, but also obtain a stronger, neater, more compact, and durable arrangement, and at much saving of expense, for, the sink being an article of manufacture and merchandise, by having added to it a veritable pump-bench or frame, is only increased in cost by the Weight of the metal added, and forms an article complete and adapted to immediate use when set up. The web I of the i metal, which forms the extension-frame, being of the same depth as the basin, forms a support much stronger than a wooden frame, while it has the advantage over that of not becomingloose or separated at the connection with the basin byfuse, and exposing 'no cracks or joilts to absorb the water and engender'oensive odors, and ultimate decay.

What we claim as our invention, and desire vto secure by Letters Patent, is-' The sinkbasin A, when constructed with flangesv a, curved or recessed on the under side to receive the ends 6 of the boards which form its support, vand ywith right-angled exterior corners, e, to correspond with the square or rectangular top of the wooden support, and the rounded interior corners d, combined and arranged substantially as and for the purposes set forth. 4

We also claim, in combination with tbe'sink basin A, the extension-frame I, 'formed of a continuationl of the sides of the basin and unge a', and provided with the shelf C, to form, in connection with said basin and its support, B, a, seat orvbeering for the pump, when arranged substantially as set Aforth. v

In witness whereof we have hereunto signed our names in the` presence of two subscribing witnesses.
